Yes, a DTS CD should play fine using a CD/DVD player connected digitally to a DTS processor. I have heard of the occasional exception with some DVD players (why it doesn't work I have no idea), but these are the exception, not the rule.

The only exceptions I have heard of are from 1st generation DVD players that were not capable of passing the DTS signal.

First-generation players will play DTS CDs, just not DVDs. The encoding for DTS CDs looks like PCM to the player; so any player that can read a standard CD should also be able to read a DTS CD. I play DTS CDs all the time in a first-generation Sony 7000.

Every CD and DVD player (regardless of generation) with a digital output should be able to play DTS CDs. I have however come across the occasional DVD player that couldn't output DTS from CD (a JVC and a Webtronic). Why they couldn't output the DTS information correctly is anyone's guess.
